Keep an eye out for these 5 Signs of Dutch Elm Disease

Dutch elm disease is one of the most destructive tree diseases in the UK and can rapidly kill infected elm trees if left unmanaged. The disease is caused by a fungus spread mainly by elm bark beetles, which carry the infection from tree to tree. It can also spread through interconnected root systems between nearby elms.

For homeowners, estates, landowners and commercial properties in Henley-on-Thames and surrounding areas, early action matters. An infected elm can quickly become structurally weakened, leading to falling branches, deadwood and eventually full tree failure. Diseased trees may also increase the risk of spreading infection to nearby elm populations in the local area.

If you suspect Dutch elm disease, professional inspection and management can help reduce safety risks and prevent further spread.

At Goldleaf Treeworks Ltd, we provide professional tree surgery services across Henley-on-Thames, Reading, Marlow, High Wycombe and surrounding areas.

Yellowing & Wilting Leaves

One of the earliest signs of Dutch elm disease is clusters of leaves turning yellow, wilting and falling during the growing season rather than autumn. This often starts on isolated branches before spreading through the canopy.

Shoots Dying Back

Smaller branches and shoots may begin dying from the tips first. You may notice sections of the crown thinning out or appearing bare during spring and summer.

“Shepherd’s Crook” Twigs

Infected twigs can bend over into a hooked shape, commonly referred to as a “shepherd’s crook”. This is a common symptom seen on affected elm trees.

Dark Streaks Under The Bark

If bark is peeled back on infected branches, dark brown or purple streaking may be visible in the outer wood. This is caused by the fungus spreading through the tree’s water transport system.

Dark Rings Inside Cut Branches

When infected branches are cut, dark rings or spotting can sometimes be seen inside the wood. This internal staining is another common indicator of Dutch elm disease.
